When you are ill, you must be unhappy because your body becomes hot, and there are pains all over. You don't
want to work; you stay in bed, feeling terrible.
What makes you ill? It is germs(细菌). Germs are everywhere. They are very small and you can't find them with
your eyes, but you can see them with a microscope. They are very small and there could be hundreds of them on or
in a very small thing.
Germs are always found in dirty water. When you look at dirty water under the microscope, you will see them in
it. So your parents will not let you drink dirty water.
Germs are found not only in water. They are also found in air and dust(灰尘). If you cut your finger, and if some
of the dust goes into the finger, it will become big and red, and you will have much pain in it. Sometimes germs will
go into your body and you will have pain everywhere.
